Tuning the self-assembly of lanthanide triple stranded heterobimetallic helicates by ligand design

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

The heterobitopic ligands LAB4 and LAB5 have been designed and synthesised with the ultimate aim of self-assembling dual-function lanthanide complexes containing either a magnetic and a luminescent probe or two luminescent probes emitting at different wave ...

A Novel Strategy for the Design of 8-Hydroxyquinolinate- Based Lanthanide Bioprobes That Emit in the Near Infrared Range

Jean-Claude Bünzli, Caroline Vandevyver

A new polydentate tripodal ligand T2soxMe was synthesized to take advantage of the chelating effect of tridentate 8- hydroxyquinolinate subunits. Potentiometric and spectrophotometric titrations reveal seven pKa values of between 3.7 and 10.2. In water, th ...

Mécanismes d'isomérisation et d'échange de ligand de complexes octaédriques labiles de cobalt (II)

Fabrice Riblet

There are only few structural thermodynamic and kinetic studies on labile octahedral complexes available today. Octahedral paramagnetic compounds of cobalt(II) have an optimum electronic relaxation leading to NMR spectra with good resolution. Therefore, th ...

Selective Self-Assembly of Hexameric Homo- and Heteropolymetallic Lanthanide Wheels: Synthesis, Structure, and Photophysical Studies

Jean-Claude Bünzli, Marinella Mazzanti

A rational approach to the formation of pure heteropolymetallic lanthanide complexes that uses a two-step assembly strategy and exploits the different size requirements of the two metals included in the final structure is described. The investigation of th ...

Lanthanide Complexes with a Calix[8]arene Bearing Phosphinoyl Pendant Arms

Jean-Claude Bünzli, Anne-Sophie Chauvin

The phosphinoyl-substituted macrocyclic receptor B8bL8, derived from p-tert-butylcalix[8]arene, was synthesized and its structure was studied in solution. According to temperaturedependent 1H and 31P NMR spectroscopic data, the calix[8]arene adopts a so-ca ...
